The mom couldn't get to her through the smoke and flames. Nor could two others - an off-duty firefighter and an off-duty police officer, who is also a neighbor.

"Before the fire department arrived we actually had a Philadelphia police officer, who lives across the street, off duty, attempt to make a rescue, but was driven back by fire and smoke," said Fire Commissioner Adam Thiel.

A 40-year-old woman and 5-year-old girl were critically injured in a house fire in Northeast Philadelphia.

An off-duty firefighter also unable to penetrate the smoke to get to the child.

"It was horrible. Her mom ran in there several times to try to save her. She just was coming out black from head to toe. She couldn't breathe," said neighbor Maren DiJoseph. "My heart was just breaking for them."

Firefighters were eventually able to bring the little girl out, and the fire was brought under control just before 6 p.m.

"She's 5 years old. That's it. Just hope for the best," Sophia's uncle, Robert Olsen, tearfully told Action News Friday. "We're a small family. We keep to ourselves. It's just a tragedy."

The victims were initially taken to Aria Health/Torresdale. The mother was later transferred to Temple and the child to St. Christopher's.

The off-duty officer was also injured trying to rescue the child. Has has been treated and released from the hospital.

The off-duty firefighter was not hurt.

Fire officials said Friday they were not able to find any working smoke detectors in the home.
